Modernization of the deeper "Świdrak"

The "Świdrak" grab dredge has been modernised. A complete reconstruction of the dredger was carried out by "Etmal".

The work carried out will significantly improve the stability of the unit and increase the efficiency of its operation.

The reconstruction consisted in the insertion of hydraulically driven piles, which, after leaving the unit, stabilize the unit, leaning against the bottom. The large size of the structure required advanced design, calculations and technical preparation. The applied, modern technological solutions will ensure durability and ease of operation of the equipment.

- The pile drives are hydraulic. In the engine room, we installed a generator with sufficient power to supply 2 hydraulic pumps. The piles are 20 metres high and can anchor the unit to a depth of about 15-16 metres. The comprehensive reconstruction also included the execution of electrical installation and wireless control system. Installation works on Świdrak took about 7 weeks.
